The National Science Foundation (NSF) annually publishes information generated by its survey of research and development (R&D) expenditures by United States industry. These data are collected for NSF by the U.S. Bureau of the Census. Other organizations also publish information on industrial R&D expenditures collected by surveys or derived from secondary sources. They include: (1) U.S. Securities and Exchange Commission; (2) "Inside R&D" newsletter; (3) "Business Week" magazine; (4) McGraw-Hill Publications Company; (5) "Research and Development" magazine; (6) Battelle Memorial Institute; and (7) Industrial Research Institute. This report examines NSF's annual survey and the seven additional sources of information on R&D spending and related activities. It includes a description of the information provided by each source, the definitions of R&D used, and the extent of coverage of the industrial sector. The report then proceeds to compare these items with those of the NSF survey. Information on how NSF and the seven other sources treat domestic R&D spending by foreign firms is included. (JN)
